Here is one I couldn’t get to shell because there were sections where I had integrated fillet features into a spline shape.
THIN FEATURE SOLIDWORKS 2017 CAP ONE END MANUAL
In the end, this shell had to be done manually, using solid bodies to represent the interior passageways, and even using the Indent feature to create shells around the holes, and some manual extruding to fill in undercuts. This might be hard to visualize, but you can imagine that with internal faces to shell around, the shell is much more complex than just shelling around exterior faces. In this case, the shell failure is due to internal cavities inside the block, and when you shell it, SolidWorks would have to create multiple bodies to do the shell. Most shell failures are due to curvature. The thing is that there is no uncontrolled curvature here. This part is all straight lines and circles, except where some draft turns a circle into an ellipse.
The shell consumes the fillet faces on the shell.īut then there are other cases that should be simple, but don’t work, like the one to the left here. Like what happens when you have a box with a fillet on a corner and the shell is thicker than the fillet. When he said “consume”, I assumed he meant “eliminate”. I’m taking the Offset and Shell to be roughly the same thing for the purposes of this discussion. The conversation is worthwhile, and I just wanted to share some specific cases I have.įirst, I must have misinterpreted something, but the topic said ‘Offset Surface “consume surface function”‘. There’s a bit of a conversation over on the Top10 site going on about the Shell feature.
